MESSRING Adds Accredited Seat-Belt-Force Calibration

MESSRING GmbH’s in-house laboratory in Gilching now holds accreditation from the German Accreditation Body (DAkkS) under DIN EN ISO/IEC 17025:2018 for one measurement quantity: seat-belt force. The accredited scope covers calibration of seat-belt-force sensors, devices used to measure the force carried by a restraint belt.

What does the accreditation establish?

MESSRING says the accreditation confirms the laboratory’s technical competence and impartiality in testing and calibration. The company presents this as compliance with internationally recognized standards for laboratory quality and impartiality.

ISO/IEC 17025 supplies the named framework, while “seat belt force” defines the measured quantity. That boundary matters: the announcement does not present the accreditation as blanket approval of every MESSRING measurement activity.

Calibration results issued under the accreditation are internationally recognized and mutually accepted by national accreditation bodies that are members of the International Laboratory Accreditation Cooperation (ILAC), the company says. For customers operating across borders, that recognition can simplify report acceptance. In plain terms, buyers can obtain an internationally recognized seat-belt-force calibration from one named laboratory.

What changes at the Gilching laboratory?

MESSRING now offers calibration of seat-belt-force sensors under its own DAkkS accreditation and performs that work directly in the Gilching laboratory. The company identifies three customer benefits: direct processing, shorter lead times and documented proof of quality under international standards. It also describes the resulting measurement chain as fully traceable and highly precise.

Here, traceability means that the reported result has a documented link to the accredited calibration process; it does not, by itself, publish the size of measurement uncertainty. MESSRING presents the in-house operation as a way to build measurement-technology expertise. Less routing, at least in theory. Shorter lead times remain a company statement, because no comparative schedule appears.

Christian Salm, Co-CEO of MESSRING GmbH, said:

“With this accreditation, we are adding a key element to our service portfolio. Our customers benefit from direct processing, shorter lead times, and clear proof of quality in accordance with international standards.”

“At the same time, we are strengthening our expertise in measurement technology and creating the foundation for offering additional accredited calibration services in the future,” he said.

For buyers, the present change is where the calibration happens, not evidence of an improved sensor reading.

How precise is the calibration?

The release supplies no force range, accuracy class, resolution, measurement uncertainty, repeatability, drift, reference standard or calibration interval. It also provides no test conditions, calibration data or before-and-after comparison. “Highly precise” and “internationally recognized” are claims in the announcement, not numerical performance results readers can check.

The 2018 in DIN EN ISO/IEC 17025:2018 is a standard revision, not an accuracy specification. It tells buyers which conformity framework governs the listed calibration scope; it does not tell them how close a sensor reading must be to a reference value.

Those details remain unstated, so buyers must request the laboratory’s applicable scope and uncertainty information before setting an acceptance criterion. For buyers, the accreditation status is clear; the precision specification is not.

What comes next?

MESSRING plans to broaden its accredited calibration scope to additional product-relevant measurement quantities. The company says this will provide a wider range of DAkkS-compliant calibration solutions, while Salm frames the present accreditation as the foundation for more accredited services. No new quantities, dates or accreditation milestones have been announced.

The sequence is straightforward, at least on paper: one accredited quantity now, more to follow. The timetable remains blank. Buyers can treat seat-belt-force calibration as available under DAkkS accreditation; buyers planning another measurement need MESSRING’s future scope before treating it as accredited.

MESSRING directs readers to www.messring.de for further information. The announcement establishes accreditation status, but not the laboratory’s performance specification. The adoption question remains concrete: does the documented uncertainty, traceability chain and turnaround meet the acceptance criteria for the customer’s exact seat-belt-force application?
